Synopsis

Description

ipcrm removes one or more messages, semaphores, or shared memory identifiers.

Options

The following option is supported:

-qmsqid

Removes the message queue identifier msqid from the system and destroys the message queue and data structure associated with it.

-ssemid

Removes the semaphore identifier semid from the system and destroys the set of semaphores and data structure associated with it.

-Mshmkey

Removes the shared memory identifier, created with key shmkey, from the system. The shared memory segment and data structure associated with it are destroyed after the last detach.

-Qmsgkey

Removes the message queue identifier, created with key msgkey, from the system and destroys the message queue and data structure associated with it.

-Ssemkey

Removes the semaphore identifier, created with key semkey, from the system and destroys the set of semaphores and data structure associated with it.

The details of the removes are described in msgctl(2), shmctl(2), and semctl(2). Use
